Fill Winding rule null is used for all pixels on the screen?
Hello
I wanted to know this questions so I can better understand the operation in general programs Illustrator and vector. Trying to understand how the pathfinder, I learned later the winding fill rule non-zero.
I think I understand that it is used to determine what parts of an object is filled when his path crosses itself or what other objects cross with her. Whenever the number of winding is not 0, it means that he went through something, that makes the number 1 coil. If it crosses this line again in the opposite direction, the winding number gets subtracted once again, so you have 0 again. Fill if the number is different from 0.
But, my question is this. This made only of pixels IN a form, to determine if there is a hole inside... or if it actually makes for every single pixel in your file, whenever you open a file, for each pixel on the screen, it uses the rule fill winding non-zero?
For example, if you make a small circle in the middle of your screen, is each pixel on the screen tested with the winding fill rule nonzero in order to determine whether a pixel is part of the circle?
Thank you.
I found it it seems.
If anoyne wants to know
-Vector programs determines how many pixels on the screen
-It creates shapes with a formula, circle, square, Bézier formulas
for simple objects without intersection he uses limit fills, he chooses a pixel of seeds within the object
It checks the 4 or 8 next to it
She fills until it finds an edge
no simple forms, it checks each pixel on the screen with a number of winding

I have created a form to fill out that is a contract, but I need a way for the person who is to fill the form to insert their logo. Is it possible for someone to insert a logo when you fill out the form to fill out? I'm looking for all the options under the button 'add a text field.
It is not possible within a text field, either. If they have Acrobat, they can use the built-in under Tools - editing content Add Image tool.
If they drive XI or higher, they can use a button form field you will need to set up for them, but the image must be in PDF format.

What version of Premiere Elements you are using and on what computer operating system is running?
You cannot import a project file (.prel) in another.
For now, generalize choice
a. export your Timeline (your intro) content to a file saved on the hard drive of the computer. And then import that
file in new projects by using the new project add Media/files and folders. See publish + Share/computer/and the other
choices here to generate this file intro for later use in other projects.
b. you can set up what is called a dummy projects - this is a project with nothing other than the intro file. And, at all times
you want to use the intro, you open one of these saved dummy projects and add your media sources.
A lot of things to discuss. Please fill in some details more and then we can refine the answer for your particular situation.
Thank you.

I bought an iphone6s from Lithuania, EU. At the back of the box, it is printed "Aproved for use in all countries of the EU". Does this mean that I can't use it in Asia?
It does not mean that you cannot use it in Asia. It cannot be repaired in the European Union, however, and may not work with LTE networks in other parts of the world.

When I use the library function node call in real time, is loaded only once for all or load the DLL every time when it is called?
I have a critical application in real time, in which I use a piece of DLL function developed in C++. It is ok? Make sure any senior developer?
Thank you in advance.
The user interface thread is the thread that is used to update the user interface. It's slow. And it's supposed to be that way because humans are slow.
The call library function node can be configured as this thread to use in the configuration for it dialog box. Please visit the LabVIEW documentation on how to do this.

Runing a code with your doc that you note possible occurrences (groups, the elements anchored, locked, etc items)
This presupposes to exclude grouped and docked:
capset (); function capset() { var mDoc = app.activeDocument, // anchored or grouped items excluded myGraphics = mDoc.splineItems.everyItem().getElements(), picContainer, gb, myCaption; while(picContainer = myGraphics.pop() ) { // exclude empty frames if (!picContainer.graphics.length) continue; gb= picContainer.geometricBounds; // add a frame to to picture's parent, which is a Page myCaption = picContainer.parent.textFrames.add (); // set position and size of the caption myCaption.geometricBounds = [gb[2], gb[1], gb[2]+3, gb[3]]; // add placeholder contents myCaption.contents = "Caption"; mDoc.groups.add ([picContainer, myCaption]); } }

Can I programmatically change the default property to create for all elements of the front panel?
I need to make the logout button, when click on, takes care of all the default values of my fron Panel.
There is no way to programmatically call the functionality of an editor 'Use default' or 'Load Default'. To do it yourself, you will need to write your default values for each control explicitly in the diagram, when the user press the logout button.
